NEW SEMICONDUCTOR FROM POLYACRYLAMIDE-CU++ CHELATE AND IODINE

In order to develop easily processing organic semiconductors the authors employed in reported experiments polymers as a base which can be easily processed and chemically modified so as to obtain good electric conductivity. They tried to produce a new type of semiconductor comprised of the mixed systems of both metal chelate and charge-transfer complexes by using easily processing polymers. In this paper a preparative method for a new organic semiconductor with a combination of polyacrylamide-metal chelates and iodine is described. Electric conductivity of the sample was measured according to the four-terminal method by using aluminum foil as electrodes. Results are tabulated and briefly discussed. It is demonstrated that iodine mounted on the chelate film also affected the property, and more than 1. 0% of iodine was necessary for the introduction of good conductivity into the film.
